A USB-Powered BB Sniper Rifle

This sniper rifle(about $100) is powered and aimed via a USB connection to your computer, and it actually has a camera built in letting you see your targets on-screen instead of having to get up and expose yourself to retaliation.You can only shoot things that are near your computer unless you feel like running around with a laptop in one hand and the gun in the other. Watch the video of it in action.
